Corel Marketplace broken - New registration not possible.

Currently Corel Marketplace ( for CorelCAD users ) does not allow new users to register - the result of attempting to register is an AJAX error that says it cannot submit the information -

Does anyone know of a workaround to this so that Corel CAD users can submit common helpful resources to CorelCAD for others to use?

Enter Email address.

Fill in form that pops up - Error comes on submit - cannot proceed past this point -

Thanks
